1. Standardization and Modularity
The GELS-Y integrated digital control logging system applies a standardized and modular design across both hardware and software, whether it's for probes, ground boxes, signal measurement, or signal transmission. The advantages of standardization and modularity include excellent product consistency, high maintainability, and enhanced reliability. The system is easy to operate and maintain, with fully universal accessories that allow for easy expansion.
2. Fully Digital Underground Signal Transmission
All signals from the underground probes are converted by A/D and encoded before being transmitted to the surface. The communication between the underground probes and the ground system is bidirectional. Digital signal transmission significantly improves anti-interference capabilities, and the system itself includes error correction to ensure high-quality signal transmission.
3. Oversampling Technology for Maximum Formation Information
The GELS-Y system uses oversampling technology to gather formation information. The oversampling rate increases as the logging speed decreases, ensuring effective digital filtering, improved spatial resolution, and enhanced identification of useful information.
4. Small-Sized Underground Probes with High Pressure Resistance
The GELS-Y probes have a diameter of approximately Φ40 or Φ50 mm, with lengths between 1000 and 1500 mm. The probes are made of stainless steel and can withstand water pressure of 20–40 MPa and temperatures of 70–90℃. Special orders can be made for probes withstanding up to 60 MPa water pressure and temperatures up to 120℃.
